Create a new article, e.g. BRWiki:Policy/My policy proposal:
{{Policy/Proposal}}

Introduction text, if you want to write one

== The Policy ==
Do this, or don't do that...

== Reasoning ==
I feel that this is needed because ....
The page will look something like this:

This is a policy proposal and requires a vote to be ratified or rejected by the policy process. Please vote in the discussion area after you have reviewed the proposal. Comments should be added to further explain Yes or No votes. Introduction text, if you want to write one The Policy Do this, or don't do that... Reasoning I feel that this is needed because ....

{{Policy/Proposal}} automatically places the page in Policy proposals.

To add your proposal to an existing proposal's talk page rather than making it a standalone article, follow the instructions for a standalone policy proposal, but do it in the  discussion  page of an existing policy.
Note however that it becomes much easier to spot new policy proposals up for vote in Votes in progress and Policy proposals if you create a new article rather than just append to an existing talk page. Creating new articles is by far the preferred method of proposing new policy as well as changes to existing policy.

In the  discussion  page of the proposal (after your proposal if you wrote it in the talk page rather than standalone), add the following:
{{
subst
:Policy/Talk}}
This will pull in {{Policy/Vote}} and create an editable voting booth:

Template:policy vote content Policy ratification vote ;Yes: ;No: Comments

{{Policy/Vote}} automatically places the talk page in Votes in progress.
Since you are the one proposing the policy, you will likely want to follow the instructions that appear to vote in favor of your own proposal.
If your proposal is a stand-alone one, you may also want to insert a * See [[BRWiki:Policy/My Policy Proposal]] above the voting booth to make it easier to find for people finding your vote via Votes in progress (which points to the talk page rather than the proposal itself).
If you would like to draw more attention to your proposal, you can show it in the community portal by adding it to Community Portal/Democracy.

If you disagree with an adopted BRWiki policy, you can start a vote to recall it.
In the  discussion  page of the proposal, add the following:
= Vote to Recall =
Your reason for wanting to recall this policy

{{
subst
:Policy/Recalltalk}}
This will pull in {{Policy/Recall}} and create an editable voting booth:

Vote to Recall Your reason for wanting to recall this policy Template:policy recall content Policy recall vote ;Keep: ;Recall: Comments

{{Policy/Recall}} automatically places the talk page in Votes in progress.
Since you are the one proposing the recall, you will likely want to follow the instructions that appear to vote in favor of recalling the proposal.
If you would like to draw more attention to your recall vote, you can show it in the community portal by adding it to Community Portal/Democracy.
